Classification3.1 Type IQuick-setting emulsified asphalt suitable forcontinuous exposure to water within a few days after applica-tion and drying.3.2 Type IIEmulsified asphalt suitable for continuousexposure to the
5、weather, only after application and drying.4. Materials and Manufacture4.1 Emulsified asphalt used as a protective coating for metalshall consist of asphalt, water, and emulsifying agents.5. Composition5.1 Emulsified asphalt complying with this specificationshall conform to the requirements in Table
6、 1.6. Performance Requirements6.1 UniformityThe emulsion shall be homogeneous. Aftera thoroughly stirred sample has been held at 10C (50F) in aclosed container for 48 h, there shall be no separation of water,coagulation of the asphalt base, settling, or packing in thecontainer that cannot be overcom
7、e by moderate hand stirring.6.2 ConsistencyThe emulsion shall be of a consistencythat will spread readily and permit application by brush, mop,or trowel at the rate of 1.0 L/m2(2.5 gal U.S./100 ft2)tovertical metal surfaces at ambient temperatures above 10C(50F). See Section 17 of Test Methods D 293
8、9.6.3 StabilityThere shall be no coagulation during thecement addition or at the conclusion of the 1-min mixingperiod.6.4 The emulsion shall conform to the additional require-ments prescribed in Table 2.7. Sampling and Test Methods7.1 Sample the material, and determine the properties enu-merated in
9、this specification in accordance with Test MethodsD 2939, except for stability and flexibility.7.2 Stability:7.2.1 MaterialHigh-early-strength portland cement con-forming to the requirements for Type III of SpecificationC 150, and having a minimum specific surface area of 1900cm2/g (133 556 in.2/lb)
10、.7.2.2 Procedure:7.2.2.1 Place about 200 g of emulsion in a tared 500-mLround-bottom porcelain dish, and weigh.7.2.2.2 Add 25 mass % portland cement based on theweight of the emulsion, in small portions while stirringconstantly with a stiff spatula.7.2.2.3 Add small amounts of distilled water if the
11、 mixturebecomes too stiff to be workable.7.2.2.4 After addition of all the cement, stir the mixturethoroughly for 1 min.7.2.2.5 Watch for any sign of coagulation of the asphalt baseduring addition of the portland cement and after the 1-minstirring period.1This specification is under the jurisdiction
